IMPROVEMENT 1N Panam-FILTERS.

The Schedule referred to in these. Letters Patent and making part of thesame.

I, MONTGOMERY P. SIMoNs, of the city of. Philadelphia,'and State ofPennsylvania', have invented a new and useful Improvement inFaucet-Filters, of which the following is a specification.

The nature of my invention consists of a faucet having a ilteringchamber in front of the key, and the latterhaving three-way openingsconstructed and arranged in relation to the main water passage, and asupplemental water way, in such Aa manner that by a certain adjustment'ofthe key the said supplemental passage is closed, and the water passesthrough the main passage' and is iiltered; and when it becomes necessaryto clean the filter the key may be turned so as to open thecommunication with the supplemental passage, and the main passage beingalso open with a fnllhead of water at the same time the sediment seeksan outlet through the former, whereby the lter is cleaned. By anotherchangein the position of the key the main and supplemental passages areclosed.

In the accompanying drawings, which make a part of this specificationlFigure l is a side elevation of the improved faucet, partly in secti0n.`

Figure 2 is across-section at the line a b of iig. 1.

Figure 3 is a cross-section of the key through the openings l 23.

Like letters in all the figures indicate the same parts.

A is the faucet, which has a main water passage, a', and a supplementalpassage, b, the latter being use d in cleaning out the settlin gs fromthe filter-in g chamber B, as hereinafter described.

The said chamber has a perforated plate, C, through which the waterpasses so as to keep outlarge particles of foreign matter, and also holdthe felt or other iiltering media I) in position against the gauze E.

F is a three-way key, a cross-section of which is shown in fig. 3.

Gis the handle of the key.

AWhen the filter is to be,A cleaned the key assumes the position seen infigs.. 1 and 2, the handle G being represented in full lines, the mainopenings-1 2 of the key being in line with the main passage a, andcommunicating with the contracted parts l 2', and the. opening 3 beingin communication with the supplemental passage b the water then washesthe sediment-s so as to cause them to flow backward through theperforations d of the plate C, and through the supplev mental passageb-in their discharge from the faucet.

1n drawingwater through the faucetthe key is turned one-half around, thehandle G assuming the position represented by dotted lines. Thenthe'solid part 4 of the key, as seen in iig. 3, closes thecornmunication with the supplemental passage b. Vhen the water is to bcentirely cut otf the key F is turned but one-fourth around, which bringsthe solid part 4 against the contracted passage 2.

rPhe water may be drawn for drinking and'ordinary ,purposes both at thesame time, if desired, when the handle G is in the postionrepresented byfull lines.

The faucet is made in two pieces A and A', screwed K together for theconvenience ofv inserting the gauze pie-ee E. i

It will readily befseen that the faucet may be made with but little moreexpense than acommon faucet,

Iand. presents'the novel advantage of being cleaned
